The serum concentration of active transforming growth factor-β is severely depressed in advanced atherosclerosis

DJ Grainger, PR Kemp, JC Metcalfe, AC Liu… - Nature medicine, 1995 - nature.com
Recent evidence has led us to propose that transforming growth factor-β (TGF-β) is a key
inhibitor of atherosclerosis. We show here that a population of patients with advanced …
